On my first test flight, it lifted very smoohtly and stayed stable for a minute or so, then the tail would drift, I landed and adjusted the gain on the tx and flew stable again. After a few adjustments, I checked the heli and noticed the damaged tail rotor. I have replaced it three times with the same result. The photo is from the third set. I bought it off of EBAY from someone that said they only hovered with it. I guess that will teach me from buying from EBAY.

I have replaced the servos and gyro with the same ones for the 450. I checked my tail rotor and it is turning correctly. I thought it might be harmonics from the servos causing oscillations down the tail boom to chip the tail blades.

I am in the process of going over the setup from the servos up and when I test it again, I will let you know. Thank you for your reply and help.
